Title: Annual progress report

Elementary particle physics research at the University of Illinois and at high energy particle accelerator laboratories operated by DOE is described. Major accomplishments in 1980 include: determination of the diffractive cross section for production of charmed D mesons in ..pi../sup -/p collisions at 215 GeV/c to be 20 ..mu..b; data acquisition for ..pi../sup -/ beryllium at 215 GeV/c; construction and testing of prototype muon drift tubes for the p anti p detector facility; Monte Carlo studies of the muon trigger rates, background levels and resolutions were done; results of photoproduction for 70 to 200 GeV photons gave cross-sections of 160 +- 70 nb and 390 +- 190 nb per nucleon respectively; the cross-section for photoproduction of the charmed ..lambda../sub c/ baryon was measured; and development of the FASTBUS system.
